Abstract
Description
Technical Field
[0001] This utility model relates to the field of compaction equipment technology, and in particular to a road construction foundation compaction equipment. Background Technology
[0002] Compaction devices are primarily used during construction to level and compact the foundation. There are many types of existing foundation compaction devices, most of which utilize impact and vibration to compact backfill soil in layers. They can also be used to break up road surfaces in layers using impact and vibration, for purposes such as ditching and the repair and maintenance of old road surfaces. Current compaction devices generally require manual operation by workers, who must move the device step by step to ensure proper compaction at different locations, making the operation time-consuming and labor-intensive.
[0003] Chinese utility model patent CN218233424U discloses a foundation compaction device, including a base and a movable seat slidably mounted on the base. A support seat is fixedly mounted on the top of the movable seat, and a first motor is fixedly mounted on one side of the support seat. A crank is fixedly connected to the output end of the first motor, and a connecting rod is rotatably connected to one end of the crank. The lower end of the connecting rod extends through to the bottom of the movable seat and is rotatably connected to a connecting plate. A compaction plate is provided at the bottom of the connecting plate. Support plates are fixedly mounted at both ends of the top of the base, and a second motor is fixedly mounted on one side of the support plate. A screw is fixedly connected to the output end of the second motor, and the movable seat is threaded onto the screw. This utility model, through the arrangement of the second motor, screw, guide rod, and movable seat, allows for adjustment of the position of the movable seat during compaction, eliminating the need for frequent manual movement of the device to compact different locations, saving time and effort.
[0004] Regarding the aforementioned technology, the inventors believe it suffers from the following drawbacks: The device supports the support rod with four rollers and uses locking devices on the rollers to stabilize the base. In actual use, when the tamping plate continuously impacts the ground, the rollers tend to bounce repeatedly up and down under the action of the tamping plate, easily causing the rollers to change position, thus altering the impact point of the tamping plate. Furthermore, this can easily damage the locking devices on the rollers, resulting in a poor user experience. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a road construction foundation compaction device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a road construction foundation compaction device, comprising a base, a support plate mounted on the base, a guide rod mounted on the support plate, a movable seat slidably mounted on the guide rod, and a compaction plate mounted on the movable seat. The bottom surface of the base is provided with a support rod, and the upper surface of the base is fixed with an installation rod. The bottom surface of the installation rod is provided with a first sliding groove, and the bottom surface of the base is provided with a second sliding groove communicating with the first sliding groove. A sliding rod is slidably mounted in both the first and second sliding grooves. A universal wheel is fixed to the bottom surface of the sliding rod, and a limiting component for limiting the sliding rod is provided on the base.
[0007] Furthermore, a tension spring is fixed to the upper surface of the sliding rod, and the other end of the tension spring is fixed to the inner top wall of the first sliding groove.
[0008] By adopting the above technical solution, when workers need to carry out road construction, they only need to activate the limiting component. This allows the sliding rod to move downwards and remain stable under the action of the limiting component, thereby pressing the caster wheel against the ground and supporting the base. Then, workers only need to push the base to move it, reducing the difficulty of moving the base. Furthermore, once the base has moved to the target area, workers only need to deactivate the limiting component, allowing the sliding rod to return to its original position under the action of the tension spring, thus pressing the support rod against the ground. This reduces the probability of the base changing position when workers compact the ground, thereby improving the user experience. Finally, workers only need to turn on the drive motor on the moving base to make the compaction plate periodically tap the ground, thereby performing ground repair and maintenance.
[0009] Furthermore, a limiting groove is formed on the inner wall of the second slide groove. The limiting component includes a limiting rod slidably disposed in the limiting groove, a push rod fixed on the side wall of the limiting rod away from the sliding rod, and a driving device disposed on the base for driving the push rod. The other end of the push rod extends to the outside of the base and is slidably connected. A placement groove is formed on the side wall of the sliding rod near the limiting rod. An inclined surface is formed on the edge where the inner bottom wall of the placement groove intersects with the side wall of the sliding rod near the limiting rod.
[0010] Furthermore, the driving device includes a fixed plate fixed to the side wall of the push rod away from the sliding rod, a cylinder fixed to the bottom surface of the base, and a fixed rod fixed to the piston rod of the cylinder, the upper end of the fixed rod being fixed to the fixed plate.
[0011] By adopting the above technical solution, when the operator needs to move the base, the operator must ensure that the casters are pressed firmly against the ground. At this time, the operator only needs to activate the cylinder, which will cause the piston rod of the cylinder to gradually retract, thereby causing the fixed plate and fixed rod to move towards the sliding rod. This will cause the limiting rod to gradually approach and eventually press against the inclined surface, and then the sliding rod will gradually move downward under the action of the limiting rod, thereby causing the casters to move downward and press against the ground, thus enabling the casters to support the base.
[0012] Furthermore, a first fixing hole matching the limiting rod is provided through the inner wall of the placement groove.
[0013] Furthermore, a second fixing hole matching the limiting rod is provided on the inner wall of the second chute.
[0014] By adopting the above technical solution, after the limiting rod crosses the inclined surface, the limiting rod connects with the first fixing hole and the second fixing hole, thereby limiting the sliding rod and improving the stability of the sliding rod and the universal wheel.
[0015] Furthermore, a control switch is provided on the side wall of the support plate, and the control switch is electrically connected to the cylinder.
[0016] By adopting the above technical solution, when the operator needs to open the cylinder, the operator only needs to press the control switch, thereby reducing the difficulty for the operator to raise and lower the casters.
[0017] Furthermore, an iron rod is fixed to the inner top wall of the first chute, and a magnet is fixed to the upper surface of the sliding rod.
[0018] By adopting the above technical solution, when the limiting rod and the sliding rod separate from each other, the sliding rod is reset under the action of the tension spring, thereby attracting the iron rod and the magnet to each other, which improves the stability of the sliding rod at this time and increases the probability that the limiting rod is aligned with the inclined surface after reset, thus improving the user experience of the staff.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, when workers need to carry out road construction, they need to activate the limiting component, which allows the sliding rod to move downwards and remain stable under the action of the limiting component, thereby pressing the caster wheel against the ground and supporting the base. Then, workers only need to push the base to move it, thus reducing the difficulty of moving the base. Furthermore, after the base moves to the target area, workers only need to deactivate the limiting component, which allows the sliding rod to return to its original position under the action of the tension spring, thus pressing the support rod against the ground, thereby reducing the probability of the base changing position when workers compact the ground, thus improving the user experience. Subsequently, workers only need to turn on the drive motor on the moving base to make the compaction plate periodically tap the ground, thereby repairing and maintaining the ground.
[0021] 2. In this application, when the operator needs to move the base, the operator needs to ensure that the casters are pressed against the ground. At this time, the operator only needs to activate the cylinder, which will cause the piston rod of the cylinder to gradually retract, thereby causing the fixed plate and the fixed rod to move towards the sliding rod, and then causing the limiting rod to gradually approach and finally press against the inclined surface, thereby causing the sliding rod to gradually move downward under the action of the limiting rod, thereby causing the casters to move downward and press against the ground, thus allowing the casters to support the base;
[0022] 3. In this application, after the limiting rod passes the inclined surface, the limiting rod is connected to the first fixing hole and the second fixing hole, thereby limiting the sliding rod and improving the stability of the sliding rod and the caster wheel. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-5 As shown in the illustration, this application discloses a road construction foundation compaction device, including a base 1, a support plate 11, a guide rod 2, a movable seat 21, a compaction plate 3, a support rod 31, a mounting rod 4, a sliding rod 5, a caster wheel 51, a limiting assembly 6, a tension spring 8, a control switch 83, an iron rod 84, and a magnet block 9. The support plate 11 is a plate-shaped structure and is mounted on the base 1. The guide rod 2 is a round rod-shaped structure and is mounted on the support plate 11. The movable seat 21 is slidably mounted on the guide rod 2, and the compaction plate 3 is mounted on the movable seat 21. The support rod 31 is a rectangular rod-shaped structure and is disposed on the bottom surface of the base 1. The mounting rod 4 is a rectangular rod-shaped structure and is fixed to the upper surface of the base 1. The bottom surface of the mounting rod 4 has a first sliding groove 41, and the bottom surface of the base 1 has a second sliding groove 42 that communicates with the first sliding groove 41. The sliding rod 5 is a rectangular rod structure, and the sliding rod 5 is slidably disposed in the first sliding groove 41 and the second sliding groove 42. The caster wheel 51 is fixed to the bottom surface of the sliding rod 5. One end of the tension spring 8 is fixed to the upper surface of the sliding rod 5, and the other end of the tension spring 8 is fixed to the inner top wall of the first sliding groove 41.
[0031] A limiting groove 52 is formed on the inner wall of the second sliding groove 42. A limiting component 6 is set on the base 1 to limit the sliding rod 5. The limiting component 6 includes a limiting rod 61, a push rod 62, and a driving device 7. The limiting rod 61 is a rectangular rod structure and is slidably set in the limiting groove 52. The push rod 62 is a round rod structure and is fixed to the side wall of the limiting rod 61 away from the sliding rod 5. The other end of the push rod 62 extends to the outside of the base 1 and is slidably connected. A placement groove 63 is formed on the side wall of the sliding rod 5 near the limiting rod 61, and an inclined surface is formed on the edge where the inner bottom wall of the placement groove 63 intersects with the side wall of the sliding rod 5 near the limiting rod 61.
[0032] The drive unit 7 is mounted on the base 1 and is used to drive the push rod 62. The drive unit 7 includes a fixed plate 71, a cylinder 72, and a fixed rod 73. The fixed plate 71 is a rectangular plate structure and is fixed to the side wall of the push rod 62 away from the sliding rod 5. The cylinder 72 is fixed to the bottom surface of the base 1. The fixed rod 73 is a rod structure and is fixed to the piston rod of the cylinder 72. The upper end of the fixed rod 73 is fixed to the fixed plate 71.
[0033] When the operator needs to move the base 1, the operator must ensure that the casters 51 are pressed against the ground. At this time, the operator only needs to activate the cylinder 72, which will cause the piston rod of the cylinder 72 to gradually retract, thereby causing the fixed plate 71 and the fixed rod 73 to move towards the sliding rod 5. This will cause the limiting rod 61 to gradually approach and eventually press against the inclined surface, thereby causing the sliding rod 5 to gradually move downward under the action of the limiting rod 61. This will cause the casters 51 to move downward and press against the ground, thus enabling the casters 51 to support the base 1.
[0034] To improve the stability of the sliding rod 5 and the caster wheel 51, a first fixing hole 81 matching the limiting rod 61 is provided through the inner wall of the mounting groove 63, and a second fixing hole 82 matching the limiting rod 61 is provided on the inner wall of the second sliding groove 42. When the limiting rod 61 passes over the inclined surface, the limiting rod 61 connects with the first fixing hole 81 and the second fixing hole 82, thereby limiting the sliding rod 5 and improving the stability of the sliding rod 5 and the caster wheel 51.
[0035] The control switch 83 is located on the side wall of the support plate 11 and is electrically connected to the cylinder 72. When the operator needs to activate the cylinder 72, the operator only needs to press the control switch 83, thereby reducing the difficulty for the operator to raise and lower the caster wheel 51.
[0036] The iron rod 84 is a round rod structure and is fixed to the inner top wall of the first sliding groove 41. The magnet block 9 is a block structure and is fixed to the upper surface of the sliding rod 5. When the limiting rod 61 separates from the sliding rod 5, the sliding rod 5 returns to its original position under the action of the tension spring 8, thereby causing the iron rod 84 and the magnet block 9 to attract each other. This improves the stability of the sliding rod 5 at this time and increases the probability that the limiting rod 61 will be aligned with the inclined surface after returning to its original position, thus improving the user experience for the staff.
[0037] The operating principle of the road construction foundation compaction equipment in this embodiment is as follows: When workers need to carry out road construction, they need to activate the limiting component 6, which allows the sliding rod 5 to move downwards and remain stable under the action of the limiting component 6, thereby causing the universal wheel 51 to press against the ground and support the base 1. Subsequently, workers only need to push the base 1 to drive it to move, thus reducing the difficulty of moving the base 1. Furthermore, after the base 1 moves to the target area, workers only need to close the limiting component 6, which allows the sliding rod 5 to return to its original position under the action of the tension spring 8, thereby causing the support rod 31 to press against the ground, thus reducing the probability of the position of the base 1 changing when workers compact the ground, thereby improving the user experience. Subsequently, workers only need to turn on the drive motor on the moving seat 21, which allows the compaction plate 3 to periodically tap the ground, thereby repairing and maintaining the ground.
[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
